Abstract: 507,730. Centrifugal extractors; washing - machines. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 3, 1938, No. 31821. Convention date, Nov. 3, 1937. [Class 23] [Also in Group VIII] A centrifugal extractor has a receptacle 8 mounted in a carrier 12 with reinforcing walls surrounding the receptacle, the said walls being wound with wire 21e; the receptacle is removably secured to the carrier by a wing nut 19. The arrangement is shown applied to a washing machine of the type described in 472,149. A vertical shaft 6 extends through a sleeve 5 rising from the base of the tub 1 and is guided by a bearing 7 with a spherical seat. The receptacle 8 is made of thin non-corrosive metal; it has imperforate tapered walls and carries at the,top an annular guard ring 9 with perforations 10 for the discharge of liquid. The carrier 12 has arms 13 radiating from a central disc 14 ; its body is formed by a strip of sheet steel 21c, bent and welded. Wires 21e which may be of galvanized steel, are wound on the body between flanges 21a, 21b, and the disc 14 is secured to the hub 15 by means of screws 17. An agitator 30 may be placed over the top of the shaft and is held by a spring clip 37. The mechanical operating arrangements are similar to those described in Specifications 452,402 and 472,149. When the shaft is oscillated the agitator 30 oscillates with it, but the movement is not communicated to the receptacle. When however the shaft is rotated for the drying operation, a centrifugal clutch holds the hub 15 to the shaft and the receptacle 8 is rotated.

Abstract: 485,584. Presses for separating liquids from solids. OLYMPIA OIL & CAKE CO., Ltd., and WESTON, P. D. Nov. 20, 1936, No. 31860. [Class 46] In a machine for expressing oil from seeds of the type comprising a rotary drum 5, Fig. 3, and an endless chain band 6 moving in a path which gradually approaches the drum, the links of the chains are such as to form a continuous smooth operating surface with passageways for the escape of the expressed oil and the operative portion of the band is supported by rigid guides 11, 12. The links of the chains are pivoted on gudgeon pins 21 which extend across the width of the band and have rollers 10 at each end engaging the guides 11, 12, which are fixed to the end frames of the machine. As shown in Fig. 6, each link 30 is in the form of a plate arranged edgewise to the drum 5 and is pivoted on two gudgeon pins 21, the links of one chain being staggered relatively to those of the adjacent chain. The links are spaced by projections 28 on their edges and may be concave on their working surfaces. Fig. 8 shows an alternative form of chain with links 50 " halved together" and separating bosses 51 around the gudgeons to space adjacent chains. The material is fed through a hopper 36 to the space between the chain band and the drum. The expressed liquid is collected by a trough 38. The solid matter is detached from the drum by a scraper 43 and delivered on to a shoot 39. The chain band is cleared by fingers 42 on a rotating member 40, the fingers entering the spaces between the ends of the links, as the links open out in passing round the sprocket wheel 8. The shaft 4, Fig. 1, of the drum is mounted in bearings 3, each of which can slide outward from the chain band against the pull of springs 18, operating on a pivoted frame 19, which engages rods 20 adjustably connected to the bearings. The drum 5 may be formed with longitudinal grooves and may be perforated. Specifications 5170/04, [Class 34], 20679/11, 248,432, [both in Class 46], 350,509, and 403,242 are referred to.

Title: Improvements in or relating to undercarriage legs for aircraft
Inventor: ROY ROBERT
IPC: B64C25/44
Filed: 1955-11-10
Abstract: 800,236. Aircraft undercarriages. BRITISH MESSIER, Ltd. Nov. 9, 1956 [Nov. 10, 1955], No. 32238/55. Class 4. A telescopic undercarriage leg for aircraft comprising a casing attached to the aircraft structure and a wheel-carrying sliding tube telescopically displaceable with respect thereto, has a coiled pipe, capable of axial extension and contraction, extending within the leg and connections between one end of the coiled pipe and the casing and the other end and the sliding tube so that pressure fluid for operating wheel brakes may be conveyed by the pipe through the interior of the leg. A cylindrical casing 12 supports a sliding tube 13 formed at its lower end with a wheel-carrying fork 14 and connected to the casing by a conventional scissors linkage 20. The tube slides within the casing on plain bearings 33 and 34 and when fully extended a flange 32 on the tube engages a thrust bearing 30. A hydraulically operated lock 35 is provided to hold the tube 13 in the extended position and a further hydraulic lock 24 secures a normally rotatable sleeve carrying the the upper pivot 21 of the linkage 20 to the casing 12 to prevent castoring action of the wheel when necessary. The upper end of casing 12 carries a tubular extension casing 37 apertured at 38 at its upper end to accommodate an end part 45 of a hollow piston rod 42 which terminates at its lower end in a piston 43 housed in tube 13. A further piston 62 is slidably mounted within piston rod 42 and is secured to a tube 65 which passes down through piston 43 for attachment to a partition member 66 which has a tubular extension 68 secured at 70 to the lower end of tube 13. Part 45 is bored at 46 and 47 for a pneumatic connection 93 and a hydraulic connection 60, the former connecting with an oleo charging pipe 92 and the latter with a coiled pipe 78 which extends through the interior of rod 42 for connection at its lower end to a further pipe 85 which terminates inside extension 68. A duct 88 in the lower end of tube 13 connects the interior of extension 68 with an external connection 89. Connection 76 is connected to a source of pressure fluid and the wheel brakes are connected to connection 89 so that the brakes may be operated through a pipe mounted within the leg. The coiled length of pipe accommodates telescoping movements of the leg and relative rotation between casing 12 and tube 13 is permitted by a rotary joint between connection 60 and bore 47. The piston rod 42, piston 62, piston 43, tube 65, member 66 and tube 13 form a known type of hydraulic-pneumatic shock absorber.

Title: Amplifier arrangement with zeroing device for piezoelectric trans ducers

Filed: 1973-07-06
Abstract: 1384856 Piezo-electric crystal amplifiers KISTLER INSTRUMENTE AG 6 July 1973 [28 July 1972] 32400/73 Heading G1N [Also in Division H3] A Piezo-electric transducer 51, Fig. 5, is connected to a high input resistance amplifier 54 whose output may be zeroed by a control signal applied to semi-conductor 57. The semi-conductor may be a MOSFET whose resistance is either controlled so as to act as an on-off device or so as to vary in steps between an on and an off state. The semi-conductor may alternatively be a pair of back to back light sensitive diodes and an associated light source, Figs.6, 8, 11 (not shown), or a device affected by a magnetic or electric field or by heat. The transducer, amplifier and semi-conductor are mounted in a common housing, Fig.12 (not shown), which is connected to a remote power supply. The zeroing is carried out before a measurement of the transducer signal is made; for a two wire connection between the power supply and the housing an arrangement such as Fig.7 is used. Here the semi-conductor is FET 74 and the amplifier is a MOSFET 75; when no power is supplied from supply 79 the FET 74 is of low resistance, i.e. the zeroing is effected. By supplying power the FET 74 is turned off via resistor 76 and capacitor 73 at a predetermined rate and the amplified transducer signal is measured as a charge via capacitor 81 in the power supply. The output can also be measured by observing the total current supplied, Fig.10 (not shown). Four wire operation is also possible, Fig.9 (not shown).
